Overview

The HP C4900A is the genuine OEM black and yellow printhead for the HP 940 ink system, used in the Officejet Pro 8000 and 8500 series printers. Unlike ink cartridges, which simply hold ink, the printhead is the precision component that fires microscopic droplets onto the page. Over time, printheads can wear out or clog beyond what automatic cleaning cycles can fix, leading to streaked, faded, or incomplete prints. Replacing the C4900A restores the black and yellow channels to factory-quality performance.

Installation is straightforward—users open the printer's cartridge access door, remove the old printhead, and snap the replacement into place. Because this unit only handles black and yellow, owners who also experience magenta or cyan issues will need the companion C4901A printhead. As a genuine HP part, the C4900A is engineered to work with HP 940 ink cartridges without the compatibility concerns that sometimes arise with third-party alternatives.
